Hey guys. I picked up an 07.5 6.7L about a month ago. The other day I was leaving work, it started up fine, but my radio shut off, my windows wouldn't roll down, and I had no turn signals. I pulled over and shut the truck off. When I went to restart it, I turned the key to warm the glow plugs/grid heater/ whatever, and the truck started, but was making an awful noise, like it was continuing to try to start. I shut it off. I tried again and the same thing, I tried to put it in drive but I couldnt get it out of park. I shut it off and tried again, it made the noise but then stopped and all electronics came back on. Its happened a few times but always goes away. But today it did it while driving, not the noise, but the electronics would just come and go. It would cut off for a minute or two, and then come back for a few minutes, and a light on the dash came on. it looked like a seatbelt light, but with an airbag too. I stopped and shut it off again. I restarted it, and the awful noise came back, i turned the key back one click, the truck was still running, the noise went away and the electronics came back on. I'm really confused here and don't know where to start. Any ideas?
